NAME
cd-paranoia 9.8 (Paranoia release III via libcdio) - an audio CD reading utility which includes extra data verification
features
SYNOPSIS
cd-paranoia [options] span [outfile]
DESCRIPTION
cd-paranoia retrieves audio tracks from CDDA capable CD-ROM drives. The data can be saved to a file or directed to stan-
dard output in WAV, AIFF, AIFF-C or raw format. Most ATAPI, SCSI and several proprietary CD-ROM drive makes are sup-
ported; cd-paranoia can determine if the target drive is CDDA capable.
In addition to simple reading, cd-paranoia adds extra-robust data verification, synchronization, error handling and
scratch reconstruction capability.
This version uses the libcdio library for interaction with a CD-ROM drive. The jitter and error correction however are
the same as used in Xiph's cdparanoia.
OPTIONS
-v --verbose
Be absurdly verbose about the autosensing and reading process. Good for setup and debugging.
-q --quiet
Do not print any progress or error information during the reading process.
-e --stderr-progress
Force output of progress information to stderr (for wrapper scripts).
-V --version
Print the program version and quit.
-Q --query
Perform CD-ROM drive autosense, query and print the CD-ROM table of contents, then quit.
-s --search-for-drive
Forces a complete search for a cdrom drive, even if the /dev/cdrom link exists.
-h --help
Print a brief synopsis of cd-paranoia usage and options.
-l --log-summary file
Save result summary to file.
-p --output-raw
Output headerless data as raw 16 bit PCM data with interleaved samples in host byte order. To force little or big
endian byte order, use -r or -R as described below.
-r --output-raw-little-endian
Output headerless data as raw 16 bit PCM data with interleaved samples in LSB first byte order.
-R --output-raw-big-endian
Output headerless data as raw 16 bit PCM data with interleaved samples in MSB first byte order.
-w --output-wav
Output data in Micro$oft RIFF WAV format (note that WAV data is always LSB first byte order).
-f --output-aiff
Output data in Apple AIFF format (note that AIFC data is always in MSB first byte order).
-a --output-aifc
Output data in uncompressed Apple AIFF-C format (note that AIFF-C data is always in MSB first byte order).
-B --batch
Cdda2wav-style batch output flag; cd-paranoia will split the output into multiple files at track boundaries. Out-
put file names are prepended with 'track#.'
-c --force-cdrom-little-endian
Some CD-ROM drives misreport their endianness (or do not report it at all); it's possible that cd-paranoia will
guess wrong. Use -c to force cd-paranoia to treat the drive as a little endian device.
-C --force-cdrom-big-endian
As above but force cd-paranoia to treat the drive as a big endian device.
-n --force-default-sectors n
Force the interface backend to do atomic reads of n sectors per read. This number can be misleading; the kernel
will often split read requests into multiple atomic reads (the automated Paranoia code is aware of this) or allow
reads only wihin a restricted size range. This option should generally not be used.
-d --force-cdrom-device device
Force the interface backend to read from device rather than the first readable CD-ROM drive it finds containing a
CD-DA disc. This can be used to specify devices of any valid interface type (ATAPI, SCSI or proprietary).
-g --force-generic-device device
This option is an alias for -d and is retained for compatibility.
-S --force-read-speed number
Use this option explicitly to set the read rate of the CD drive (where supported). This can reduce underruns on
machines with slow disks, or which are low on memory.
-t --toc-offset number
Use this option to force the entire disc LBA addressing to shift by the given amount; the value is added to the
beginning offsets in the TOC. This can be used to shift track boundaries for the whole disc manually on sector
granularity. The next option does something similar...
-T --toc-bias
Some drives (usually random Toshibas) report the actual track beginning offset values in the TOC, but then treat
the beginning of track 1 index 1 as sector 0 for all read operations. This results in every track seeming to
start too late (losing a bit of the beginning and catching a bit of the next track). -T accounts for this behav-
ior. Note that this option will cause cd-paranoia to attempt to read sectors before or past the known user data
area of the disc, resulting in read errors at disc edges on most drives and possibly even hard lockups on some
buggy hardware.
-O --sample-offset number
Some CD-ROM/CD-R drives will add an offset to the position on reading audio data. This is usually around 500-700
audio samples (ca. 1/75 second) on reading. So when cd-paranoia queries a specific sector, it might not receive
exactly that sector, but shifted by some amount.
Use this option to force the entire disc to shift sample position output by the given amount; This can be used to shift
track boundaries for the whole disc manually on sample granularity. Note that if you are ripping something including the
ending of the CD (e.g. the entire disk), this option will cause cd-paranoia to attempt to read partial sectors before or
past the known user data area, probably causing read errors on most drives and possibly even hard lockups on some buggy
hardware.
-Z --disable-paranoia
Disable all data verification and correction features. When using -Z, cd-paranoia reads data exactly as would
cdda2wav with an overlap setting of zero. This option implies that -Y is active.
-z --never-skip[=max_retries]
Do not accept any skips; retry forever if needed. An optional maximum number of retries can be specified; for
comparison, default without -z is currently 20.
-Y --disable-extra-paranoia
Disables intra-read data verification; only overlap checking at read boundaries is performed. It can wedge if
errors occur in the attempted overlap area. Not recommended.
-X --abort-on-skip
If the read skips due to imperfect data, a scratch, whatever, abort reading this track. If output is to a file,
delete the partially completed file.
-x --test-flags mask
Simulate CD-reading errors. This is used in regression testing, but other uses might be to see how well a CD-ROM
performs under (simulated) CD degradation. mask specifies the artificial kinds of errors to introduced; "or"-ing
values from the selection below will simulate the kind of specified failure.

SPAN ARGUMENT
The span argument specifies which track, tracks or subsections of tracks to read. This argument is required. NOTE:
Unless the span is a simple number, it's generally a good idea to quote the span argument to protect it from the shell.
The span argument may be a simple track number or an offset/span specification. The syntax of an offset/span takes the
rough form:
1[ww:xx:yy.zz]-2[aa:bb:cc.dd]
Here, 1 and 2 are track numbers; the numbers in brackets provide a finer grained offset within a particular track.
[aa:bb:cc.dd] is in hours/minutes/seconds/sectors format. Zero fields need not be specified: [::20], [:20], [20], [20.],
etc, would be interpreted as twenty seconds, [10:] would be ten minutes, [.30] would be thirty sectors (75 sectors per
second).
When only a single offset is supplied, it is interpreted as a starting offset and ripping will continue to the end of the
track. If a single offset is preceeded or followed by a hyphen, the implicit missing offset is taken to be the start or
end of the disc, respectively. Thus:
1:[20.35]
Specifies ripping from track 1, second 20, sector 35 to the end of track 1.
1:[20.35]-
Specifies ripping from 1[20.35] to the end of the disc
-2 Specifies ripping from the beginning of the disc up to (and including) track 2
-2:[30.35]
Specifies ripping from the beginning of the disc up to 2:[30.35]
2-4 Specifies ripping from the beginning of track 2 to the end of track 4.
Again, don't forget to protect square brackets and preceeding hyphens from the shell.
EXAMPLES
A few examples, protected from the shell:
Query only with exhaustive search for a drive and full reporting of autosense:
cd-paranoia -vsQ
Extract an entire disc, putting each track in a seperate file:
cd-paranoia -B
Extract from track 1, time 0:30.12 to 1:10.00:
cd-paranoia "1[:30.12]-1[1:10]"
Extract from the beginning of the disc up to track 3:
cd-paranoia -- "-3"
The "--" above is to distinguish "-3" from an option flag.
OUTPUT
The output file argument is optional; if it is not specified, cd-paranoia will output samples to one of cdda.wav,
cdda.aifc, or cdda.raw depending on whether -w, -a, -r or -R is used (-w is the implicit default). The output file argu-
ment of - specifies standard output; all data formats may be piped.
ACKNOWLEDGEMENTS
cd-paranoia sprang from and once drew heavily from the interface of Heiko Eissfeldt's (heikoATcolossus.de)
'cdda2wav' package. cd-paranoia would not have happened without it.
Joerg Schilling has also contributed SCSI expertise through his generic SCSI transport library.
